ro troughs for printing-machines.

' In the case of the inking-troughs for print:

ing-machines which have been customary up to the resent the resilient knife is set either by the direct ressure of a set-screw or indirectly, a lever eing inserted between the set-screw and the knife. The new device is illustrated in the accompanying drawing. In the case of the new arrangement the adjustment of the inkingknife takes place only by means of two armed levers e, the arms of which on the one hand are formed as segment pieces or cams f,'which carry the inking-knife b, whereas the other longer arms project through the slits '1' 2 5 of the back. wall of the inking-trough 0. Each time that the levers are depressed the inkingknife is set against the ductor-roller a, and

each time the levers are raised the knife moves away from the roller on account of its own elasticity. It is therefore necessary merely to cast a glance at the levers in order to see how the knife stands. The correct setting of the knife is consequently extraordinarily simple to perform.

What I claim as my invention, and desire to secure by Letters Patent, is-

In combination in a printing-machine of the character described, an inkin -trough 0 having a wall provided with a p urality of slits, an inking-roller a, an inking-knife b, a plurality of lever-arms a each having a cam f engaging the inking-knife and projecting through a slit of the wall of the inking-trough and means for fixing each of said lever-arms e in any desired position, substantially and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
